In material editor drag those textures to their respective materials (so you can see the texture in texture painting mode) 4) Switch to Texture Painting 5) Enable Paint mask 6) Pain something on first cube. Only Tex1 should be affected 7) Press Shift Right Click (using RClick select) to deselect one face, doesn't matter which cube 8) Notice how Tex1 is showed on every cube 8a) I cannot paint on any other cube except the one where Tex1 is actually supposed to be 9) Tab into edit mode, Tab out, it's okay now. I searched to find similar bug posted, didn't find any, I'm sorry if this is a duplicate or if it's known issue (glanced through those).
